Filed: 2000-04-12
Abstract: PROBLEM TO BE SOLVED: To provide an efficient and industrial method for producing an optically active 3-amino-4,4-dimethyl-γ-butyrolactone which is an intermediate extremely useful for synthesis of an anticancer, an HIV protease inhibitor, or the like, having an asymmetric center. SOLUTION: A racemic 3-amino-4,4-dimethyl-γ-butyrolactone is reacted with an optically active carboxylic acid compound to provide a diastereomer salt, and the diastereomer salt is fractionated. The fractionated diastereomer salt is decomposed to provide the objective optically active 3-amino-4,4-dimethyl-γ- butyrolactone or a salt thereof. In the production method, the salt of the optically chiral 3-amino-4,4-dimethyl-γ-butyrolactone and the optically active carboxylic acid compound remaining in the mother liquor are also decomposed, and the resolution agent is recovered. The remaining antipode can be racemized in the presence of a basic compound and recovered, and the recovered racemic compound can be recycled to a step for the optical resolution with the optically active carboxylic acid compound.
